  • the support surface regions 88, 90 of the support region 78 are designed so that they project radially beyond the base outer peripheral surface 94 of the attachment shaft 26 with respect to the attachment shank longitudinal axis L B.
  • the embodiment is such that this radial projection in the central region of the support region 78, ie where the fifth transition region 92 is formed, is the lowest, so there, for example, almost no radial projection is present, while in the circumferential direction and in the direction of the fifth Transition region 92 away this radial projection increases.

  • a further significant advantage of the support surface regions 88, 90 projecting radially beyond the base outer peripheral surface 94 is that locally localized surface regions are utilized there to generate abutting contact between the attachment shaft 26, ie the bit holder 10, and the base part 44. Since both the bit holder 10 and the base member 44 are generally provided as forgings and therefore those surfaces in which a mutual support, to achieve the required precision material to be edited or reworked, this operation can be limited to the fact actually provided surface areas, namely where the support surface areas 88, 90 are formed.

  • the configuration may be such that near the sixth transition region 100 this radial projection is maximum and decreases in the circumferential direction in the direction away from the sixth transition region 100, so that gradually the counter-support surfaces 96, 98 are transferred into the basic inner circumferential surface 108.
  • the two counter-support surface regions 96, 98 are inclined with respect to each other, in this case with a curved course, this curvature being able to correspond to the curvature of the two support surface regions 88, 90 in order to achieve a large contact area.
  • the attachment shaft 26 can be introduced into the attachment shaft receiving opening 46 with lateral play in principle, it is only by moving the attachment member 82 onto the attachment member loading surface 80 that a firm abutting contact is created between the support surface portions 88, 90 and the counter support surface portions 96, 98. A leading to a stronger pressure contact of the two transition regions 92, 100 is thereby avoided.

  • a supporting surface area or counter-supporting surface area with the respective surfaces serving for mutual support is designed or processed in such a way that a direct metal-metal contact can be generated. Since both the base part and the chisel holder are generally produced as forgings, the surfaces serving as support surface areas or counter-support surface areas in the context of the present invention are thus basically manufactured and / or reworked in terms of materials. In this way, the high precision required for a substantial relief and accurate positioning of these surfaces can be ensured, which would not be feasible in a merely machined in a forging surface.
  • This process can then be repeated several times with recurring wear then, of course, in conjunction with the same set on a milling drum base part. If wear also occurs in the area of a base part, then of course this can also be done by a milling drum be solved by separating the holding this welding connection and replaced by a new base part.
